TCT Circular Saw Blade 450 × 3.5 × 40 mm, 140 Teeth
450 mm TCT blade for the largest steel section.
TCT Circular Saw Blade 450 × 3.5 × 40 mm, 140 Teeth
For cut-off machines that take a 450 mm blade and work that will not fit anything smaller. Carbide teeth hold their edge where HSS would soften, so it keeps cutting on stainless and alloy section that would blunt a steel blade in a shift.
Key Features
Carbide holds hardness at temperature
The tooth does not soften as the cut heats up — an order of magnitude more life on stainless than HSS.
Covers the largest section
450 mm reaches work no other blade in the range will take.
Needs a heavy machine
Rigidity and power have to match the blade size.
